[Also in Group X] Hardening of fresh concrete is assisted by placing an inflatable core 1 surrounded by a vacuum chamber and filtering wall 6 in shuttering in the expanded state, pouring in concrete, evacuating the vacuum chamber to draw water from the concrete, deflating the core and finally removing the vacuum. The filtering wall 6 is supported around the core by an expansible and contractible cage 20 which provides a chamber connected by a pipe 29 to vacuum. The cage 20 is formed of interlaced helices of wire or parallel tubes connected by belts, Fig. 4 (not shown). The core can be wholly immersed in the concrete up to the level of the closure 2 which carries a cap connected to vacuum, Fig. 1 (not shown). In Fig. 3, in which the core is intended to be only partially immersed, the cage 20 is completed by sleeves 23, 24 at the top and bottom, the sleeve 24 also comprising a cap 25 closing the end of the core, the sleeve 23 being connected by a metallic network to the closure 2. The core is engaged in a conduit 18 in set concrete to the level N, inflated to engage the sleeve 24 with the conduit and further concrete poured to cover the folded part of a rubber skirt 28 which seals the vacuum chamber and the concrete then treated with vacuum. To cast a further layer the core is partially deflated, the vacuum removed and the skirt 28 turned up to a higher position and further concrete poured. The skirt 28 and wall 6 may be replaced by a paper sleeve. The core may be of circular section or may be made of square section with the aid of four tubes symmetrically arranged, Fig. 6 (not shown), to form the corners.

Title: Headlamp tilting mechanism in a motor vehicle
IPC: B60Q1/105
Filed: 1975-06-06
Abstract: 1537244 Headlamp tilting systems LUCAS INDUSTRIES Ltd 28 May 1976 [6 June 1975] 24357/75 Heading F4R A headlamp tilting system for a motor vehicle includes a transmitter device 13 having one input chamber connected to a first transducer 12 having a mechanical input representative of the attitude of the vehicle body 10 with respect to an unsuspended vehicle portion 43 and a pair of separate output chambers for transmitting hydraulic signals to second transducers 14 each having a mechanical output arranged to tilt the headlamps 11. In one embodiment, Fig. 1 (and Figs. 2-4, not shown), the pair of separate output chambers in the transmitter are in sideby-side relation, with pistons 25, 26 yoked together for simultaneous movement. The system is designed to prevent "see-sawing" of the headlamps due to unequal external forces acting on each headlamp 11, e.g. from the wind. If one of the pistons 25, 26 experiences a greater force from one of the second transducers 14 than from the other, the pistons cannot move to relieve the excess pressure because of the force from a spring 41 preventing compression of the first transducer 12 and because the pistons are yoked together. The transmitter 13 may include a biasing spring acting on the yoke. In another arrangement, Fig. 5, the output chambers 323, 324 and pistons 325, 326 are mounted axially on a hollow rod 327. A bore 368 in the rod wall connects input chambers 331, 367 and the rod slides in bushes 365, 366. In another arrangement the housing is in two connected parts, only one support bush is provided and the output chambers are of equal volume (Fig. 6, not shown). In further arrangements described, the pistons engage diaphragm seals defining the ends of the output chambers (Fig. 8, not shown) or the output chambers comprise bellows elements compressible by a common plate in the input chamber (Fig. 7, not shown). The transmitter device may receive signals from two first transducers sensing the body attitude relative to front and rear wheels. The hydraulic output is then the algebraic sum of the input signals.

Patent GB-462131-A (GB)
Title: Improvements in or relating to the manufacture of hydrofluoric acid
IPC: C01B7/19
Filed: 1935-09-02
Abstract: <PICT:0462131/III/1> Hydrofluoric acid is obtained in a continuous process which comprises reacting an acid or an acid sulphate with a mineral fluoride under super-atmospheric pressure, subjecting the evolved vapours to a preliminary cooling at a temperature not below but not more than 15 DEG  C. above the boiling point of anhydrous hydrofluoric acid under the prevailing pressure, removing the condensate, and condensing the residual vapours.  The super-atmospheric pressure in the first step may be maintained by the introduction of an inert gas, e.g. nitrogen.  The steps subsequent to the first may be carried out at any desired pressure.  Suitable acids include phosphoric, fluorsulphonic and, preferably, sulphuric acid. Suitable mineral fluorides are silica-free fluorspar and cryolite. The first step of the process is preferably conducted at a temperature above 100 DEG  C., say at an initial temperature of 140 DEG  C. rising finally to 320 DEG  C. Finely ground fluorspar is introduced into a container 1 and is fed by a conveyer 5 into receivers 9 and 10 and from thence through a conveyer 11 into a closed U-shaped retort 17 to which sulphuric acid, preferably in slight excess, is simultaneously fed from a container 13 via a pipe 15.  As an alternative a paste of fluorspar and sulphuric acid formed in a premixing mill can be fed into the retort.  The retort 17 is slightly inclined, is provided with rotating radial stirring arms 20 and is heated by a furnace 28.  The resulting calcium sulphate is continuously removed by a discharge device 22 which can operate while maintaining increased pressure in the reaction zone.  The gaseous reaction products are withdrawn through a line 29, are freed from mist in a coke-filled tower 30 and pass through a line 33 into a water-cooled condenser coil 34.  The condensate consisting of dilute hydrofluoric acid is withdrawn through a line 47 to a storage tank 46.  The residual gases are washed with a portion of the dilute acid from the tank 46 in a tower 44, being thereby freed from aqueous acid in the form of mist and pass through a line 59 to a condenser H operating at say 20 DEG  C.  Concentrated hydrofluoric acid condenses in H, is separated from uncondensed gases in a trap 64, and is stored in a container 68.  The dilute acid in the tank 46 may be pumped through a line 56 into a storage tank M and from thence through a line 77 into a distillation column 80.  A less concentrated acid collects in a still pot 81, while anhydrous hydrofluoric acid is condensed in a condenser O and passes into a trap 88, from which a part is returned to the still through a line 89 to serve as a refluxing liquid, the remainder being withdrawn through a line 92. The parts of the apparatus in contact with hydrofluoric acid may be made of iron, steel or copper.  The concentrated acid in the container 68 may also be subjected to distillation if desired.
